WILLIAM WILLIAMS AND PATRICK MCMORROW, OF NEW YORK, N. Y.

DUMB-WAITER.

SPECIFICATION forming part of Letters Patent No. 600,759, dated March 15, 1898. Application filed August 10, 1897. Serial No. 647,693. (No model.)

T0 a/ZZ whom t may concern;

Be it known that We, WILLIAM WILLIAMS and PATRICK MoMoRRow, citizens of the United States, residing at the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Dumb-Waiters, of which the following is a full, clear, and exact specification.

Our invention relates to hoisting apparatus, and has for its objects more particularly to provide a dumb-waiter car for residences, apartment-houses, &c., which will not only withstand fire, but will also serve to materially reduce the draft in the shaft, so as to prevent fire from working its way rapidly upward into the building by way of same.

The objects above set forth we are enabled to accomplish by means of our invention, which consists in the novel details of construction and in the combination, connection, and arrangement of parts hereinafter more fully described, and then pointed out in the claims.

In the accompanying drawings, forming partof this specification, wherein like letters of reference indicate like parts, Figure lis a perspective view showing the construction of the car-frame set together without its sheetmetal covering. Fig. 2 is a perspective view of a complete car constructed according to and embodying our invention. Fig. 3 is a top or plan view of the car, showing the same in position within the shaft. Fig. 4 is a transverse section of the base of the car, taken on the line et 4t of Fig. 2. Fig. 5 is an enlarged detail section taken on the line 5 5 of Fig. 2. Fig. 6 is a similar view taken on the line 6 6 of Fig. 2, and Fig, 7 is a horizontal section of the car.

In said drawings, A designates the carframe,consisting of the reinforced rectangular top and base frames B and C and the vertical connecting angle-iron sections D' D2 D3 D4. rIhe top frame B and base-frame C are substantially alike, and are composed of the angle-irons E E2 E2 E4, having their horizontal surfaces uppermost and their ends Initered and secured together with the ends of the angle-iron connecting-sections D D2 D3 D4 by bolts or rivets or.

F F denote the horizontal connecting secshown at Fig. 3.

tions or braces, having their ends partly cut away and swaged down and riveted to the under side of the horizontal surfaces of the top and base frame sections E E3, said horizontal connecting-sections F F likewise being secured in position,wth the edges of their horizontal surfaces facing each other and their horizontal surfaces uppermost and in the same plane with horizontal surfaces of the angle-irons E E2 E3 E4 of the top and base frames. A sheet of metal of suitable form and thickness, bent to form the three sides G' G2 G3, is disposed within the vertical connecting-sections D D2 D3 D4 and the ends of the sides Gr' and G3 bent outwardly and then back upon the outer surfaces of the vertical connecting-sections Dl D4, as shown in Figs. 6 and 7, and the whole covering then secured to the frame by rivets h.

H I-I denote the coverings for the top and base frames B and C, respectively, these coverings being placed upon the frames B and C so as to be supported upon the horizontal surfaces of the angle-irons constituting the frames and having their edges c bent downwardiy over the vertical surfaces of said angle-irons and then rearwardly and up behind the same, and the whole then iirmly secured to the frames by means of bolts I I and rivets CZ d.

At the top of the car is a loop-bolt J, having its ends threaded and passed through openings in the covering II andthe horizontal connecting-sections F F and secured in position beneath the horizontal surfaces of said sections F F by nuts, and K K denote diagonal corner-braces having their upper ends securedito the top frame B and their lower ends to the vertical connecting-sections D D2 D3 D4 by means of bolts or rivets ffor the purpose of giving additional rigidity to the structure. l

Along the edges of the car at its top are arranged metal supporting-strips L L2 L3 L4, which project a short distance beyond the outline of the car-body. Upon these supportingstrips are disposed flexible strips M M2 M3 M4, made of rubber, asbestos, or other suitable material, which project beyond the edges of the supporting-strips and almost touch the sides of the shaft adjacent to the car, as The metal supporting-strips IOO The metal supporting-strip and the flexible strip, secured at the front edge of the car, areV provided with recesses O O', sufliciently largef to accommodate the hoisting and lowering ropes, and one of the supporting-plates and flexible strips at one side of the car are partlyj cut away to accommodate the balance-weight P and theguides Q therefor, secured to one side of the shaft.

EItwill lbe` observed that by meansof the construction shown and described the carbody proper ,will serve as a fire-,break and that by means of ythe yapparatus applied .to the top thereof the space intermediate the sides of ythe car and -the shaft will `be .substantially closed, thus preventing a y,draft from carrying the fire upwardly into Athe building.

It is obviousthat where the balance-weight guidesare wider thanherein described, and shown in the drawings, oneof the flexible stripsand the supporting-.strip therefonmay he dispensed .with at oneside of the carand that where the arrangement of lthe openings in the shaft, whereby access may be fhad to thecar, is such as to require the car to y be open at @more than one sidethe `same maybe easily accomplished without materially alteringtlie construction shown and described.

`Viithoutlimiting ourselves to the details of construction, which may be varied within the scope of the invention, whatwe claim, anddesire to secure by Letters Patent, is-

1. The combination with a shaft and car Working therein, of flexible strips secured to said car and projecting horizontallybeyond the outline thereof, and means interposedbetween the car and said flexible strips for maintainingsaid flexible strips lto theirhorizontal position to close the opening Vintermediatethe sides of the car and shaft, substantially as specified.

2. The combination with a shaft and car working therein, of flexible strips vsecured to said lcar along-the edges thereof andprojecting outwardly therefrom, and means interposed between the car and said flexible strips for supporting said fiexible strips in ltheir horizontal position beyond the outlineof the car to close the openingintermediate the sides of the car and shaft, substantially as specified.

3. The combination with a shaft and Acar workingtherein, of flexible strips, securedto the top of thecar alongits edgesY and arranged to project outwardly from said car, with their outer edges corresponding in outline withthe general outline of the shaft in cross-section, non-flexible strips disposed upon the top of the car .beneath the flexible strips, and arranged to project outwardly beyond the outline of the car, and within the outline described bythe outer edges of the flexible strips to support said flexible strips in the horizontal position, substantially as specified.

4. The combination with a shaft and car l working therein, of rubber strips arranged l 4upon `the top of the car along its edge and projecting horizontally therefrom beyond the outline of the car,of non-fiexible supportingstrips. disposed .upon the top of the car beneath the rubber strips, andprojecting beyondthe outline of the car but within the outline described by the outer edges of the rubber strips, and metal strips `disposed upon the rubber strips along their inner edges, and bolts passingthrough said metal, rubber, and supporting strips, and the top of the car, provided with nuts secured to the ends thereof upon the inner side of the car, substantially as and for the purposes set forth.

5. A dumb-waiter car comprising the top connecting-sections secured to said top andbase frames `with their horizontal surfaces uppermost, and yvertical connecting-sections having their ends secured to the top and base frames at the corners thereof, substantially as specified.

7. vA dumb-waiter Acar comprising the top andbase composed-of angle-ironlsections E', E2, E3, fE4, having their `horizontal portions uppermost, horizontal connecting-sections F,

F having their ends secured to the under sides of the horizontal portions of the angleirons E', E3, and their horizontal portions in the sameplane with those of thesections E', E2, E3, E4, sheet-.metal coverings H, H', disposed upon `-thehorizontal portions, and secured to the vertical portions of the sections E', E2, E3, E4, angle-iron connecting-sections D', D2,'D3, D4 having their upper and lower ends secured respectively to the corners of the top and base, and sheet-metal sidesG, G2, Gssecured to saidconnecting-sections D, D2, D3, D4, andthe top and base frame sections E", E2, E3, E4, substantially as specified.

'Signed at the city of New Yorlginthe county and State oflNew York, this 17th day of July, 1897.
